GAGE.

SPECIFICATION forming part of Letters Patent No. 560,781, dated May 26, 1896. Application filed May 2, 1895. Serial llo. 547,951. (No model.)

To LZZ whom it may concern:-

Be it known that I, RICHARD CONWAY, a citizen of the United States, residing at Carroll, in the county of Carroll, State of Iowa, have invented a new and useful Hinge-Gage for Setting Hinges on Doors and Jambs, of

which the following is a specification.

My invention relates to improvements in hinge-gages, especially employed for gaging on the door and jamb the Width and depth the hinge-flap is to be set into the door and jamb. It is also designed for hanging inside and outside blinds.

My object is to produce a hinge-gage that is very simple in construction, not liable to get out of order, also to entirely dispense with theuse of arms or stocks and the two-block system, (this is a very important feature of my inventiom) also that the gage can be applied to the jamb or frame with projecting moldings or where the casing is set back and where ordinary gages with arms or stocks cannot be used, and furthermore to produce a gage with but two cutters or blades and in one block, which greatly reduces the expense of manufacturing and thereby the cost of hinge-gages, and finally to produce a gageA that is very compact and small and simple in construction and operation.

My invention consists of a perforated block provided with a guide-plate, a cutter-plate and guide-plate combined, and a round bar with a cutter-point passing through said bar at one end. The bar and guideplate are made adjustable by means of thumb-screws, the guide-plate being slotted to allow it to slide back and forth. rlhe cutter-plate and guide-plate combined are made adjustable by means of a round-head screw, the plate being slotted to allow it to slide back and forth.

It also consists in the construction of certain details, which will be more fully described hereinafter, and specifically pointed out in the claim, reference being had to accompanying drawings and the letters of reference marked thereon. v

Like letters indicate similar parts in the different iigures of the drawings, in which` Figures l and 2 are perspective views of the gage, showing all the parts in their respective places. Fig. 3 is a side view of the gage,

showin g it set for marking from back of rabbet on the jamb the distance hinge-flap is set on the j amb. Fig. fl is also a side view of the gage set for marking from back of door the distance hinge-flap is set 011 the door, also set for depth of hinge-flap either on the j amb or door. Fig. 5 is an end view of the gage, showing the manner in which the thumb-screw comes in contact with bar containing cutterpoint. Fig. 6 is a face view of the combined guide and cutter plate removed from body of gage. Fig. 7 is a perspective view of bar containing cutter-point at one end removed from body of gage. Fig. 8 is a face view of guideplate removed from body of gage.

In the drawings, d represents an opening through the body of gage. c is a guide-plate having at one end a portion of it turned at right angles to itsrface t0 act as a guide in working the gage, and lo on the opposite end is a spur, which fits into groove fm and is intended to keep guide-plate parallel with body of gage.

eis a thumb-screw which passes through washer CZ and slot s in plate c and into body of gage to hold plate c at any point desired. Vasher d is to prevent dirt accumulating in slot s.

f is a cutter-plate and guide-plate combined and is placed in groove t', having at one end cutter-point j, and through it slot r, with set-screw g passing through washer h and through slot in plate f into body of gage secures them to body of gage. Washer h is to prevent dirt accumulating in slot r. Bar l), containing cutter-point 0, is fitted to slide into body of gage, with cutter-point 0 projecting through slot n, and is held at any desired point with thumb-screw p.

To operate this gage, regulate the set-screw g so plate f can be moved back and forth with thumb and finger, leaving itin the position shown in Fig. 3. Loosen thumb-screw p and slide cutter-point 0 the required distance the hin ge-flap is placed from back of rabbet, measuring from the end of gage. Loosen thumb-` screw e and move guide-plate c the distance from end of gage required for depth of hinge flap. The gage is then ready for marking in the rabbet. Slide plate f with thumb and iinger to the position shown in Fig. 4c, which sets the gage for marking depth of hinge-nap on jamb and door, also the distance hinge-Hap IOO is set from back of door, and leaving the proper space between door and back of rabbet, thus avoiding the door being hingebound.

I-laving thus described my invention, what I Claim, and desire to secure by Letters Patent, is-

A earpenters hinge-gage eomprsin g a stock grooved on its opposite sides, a slidable gage c, adjustably secured in one of said grooves, a slidable seribing-point o, adj ustably secured in the opposite groove, and slidable plate f,

adjustably secured on one end of said stock, having` a seribing-point j, on one end thereof adaptedA to ooaet with said gage c, the other end thereof forming an internal or external gaging-surfaoe for said soribing-point 0, aeeordingly as plate f, is adjusted; all oonstrueted and arranged as shown and for the purpose set forth.
